What it does

Image Service is an agent skill from zrt-ai-lab/opencode-skills. 多模态图像处理技能,支持信息图、封面图、长图、幻灯片、漫画、文章插图、小红书图、营销物料等多场景生图,以及图生图、图生文、长图拼接。

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 42 other files (for example `README.md`, `config/settings.json` and `core/image_to_image.py`).

The repository describes itself as: OpenCode/Claude Code 技能库 。特色技能:视频生成、图片生成、AI Agent 互联、智能问数等等各场景,持续开发更新中.

Example prompts

  • “/image-service”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. 生成完成后,含中文文字的图用 core/image_to_text.py -m ocr 校验文字是否清晰
  2. OCR结果与预期不符 → 用 core/image_to_image.py 迭代修复(参考 guides/text-rendering.md)
  3. 多图场景完成后,逐张展示给用户确认,不满意的单张重新生成

What it can do on your machine

Read from SKILL.md and the folder at commit d38536f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Image Service loads about 1.1k tokens when it runs. Until then it costs about 20 tokens; SKILL.md has 131 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~20
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 131 words (~1,057 tokens).
